である。この発明は、絞り弁に回転運動を伝達するため
のいゞ−系において、発動機と支持体の間の運動の影響
を取除くことを目的とする。The fact that the motor is not rigidly connected to the support allows the motor to move relative to the support, for example when operating under load. The lever for operating the aperture is
attached to the support or to an element connected thereto, and also because the engine, together with its carburetor and throttle valve, is displaced from its normal position as a result of the aforementioned relative movements. , a corresponding movement is transmitted to the throttle valve via the aforementioned levers, links, etc., thus changing the setting of the throttle valve, possibly a preset setting. The operator of the machine must therefore correct the throttle setting by means of the lever for actuating the throttle to the same setting as the throttle valve had before the above-mentioned relative movement or to another setting that the operator considers appropriate. Must be. If the engine is operated with varying loads, correction of the throttle valve setting is now required, making it difficult for the operator to consistently maintain a suitable engine speed. Therefore, there is a need for a means to enable the throttle valve to be maintained at a predetermined setting in situations where the motor is movable relative to its support. The object of the invention is to eliminate the effects of movement between the engine and the support in a drive system for transmitting rotational movement to a throttle valve.

、図面を参照しながら以下に説明する。In this regard, the rotational linkage of the throttle valve is a precise function of the change in the position of the throttle actuating lever actuated by the operator of the machine. The elimination of the influence of relative movements on the throttle valve must be adapted to the particular given mode of such movement, which is usually very specific to each type of machine. The following description describes a device for eliminating the effects of movement between the motor and the support in the case of machines in which the above-mentioned relative movement has a characteristic pattern. In the throttle valve control device of the present invention equipped with means for achieving the object of the present invention, the lever system includes two levers, one connected to the actuating member and the other lever connected to the throttle valve. levers, these two levers are each pivoted on each of the two substantially parallel balls, and each has surfaces in contact with each other, and the lesser of the two levers is Said surfaces on both levers are curved around a center of curvature located approximately at the center of pivot defined by the pivoting movement caused by the vibrations of the motor. The deployment of an embodiment of the device of the invention will be explained below with reference to the drawings.

を介して間接的に連結される。The actuating part 1 is attached to a support by an axle 3, and the motor (not shown) is supported by a vibration damping element 4 made of rubber.
It is elastically suspended on a support. The outer end of the actuating member 1 has a finger grip 5 located in a handle 6 associated with the support. A neck stop member 7 is further disposed inside the handle 6, and this stop member 7 can be configured by arranging the shoulder 8 of the actuating member 1 to face the protrusion 9 of the stop member 7 in the illustrated position. The actuating section 1 is latched at the lower limit position. When the clasp 7 is pushed down in the handle 6 so that the projection 9 slides past the shoulder 8, the latches are released. As a result, the actuating member 1
can pivot upward when pressure is applied to the finger grip 5. This pivoting movement of the actuating member 1 is facilitated by a curved first lever 101 which is fixedly connected to the actuating member 1 and extends from it and thus pivots about the axis 3. The first lever 10 has a part extending above the carburetor 11 which is integrated into the engine and is thus decoupled from the support with respect to vibrations. The underside 12 of the first lever 10 contacts, at its front part 19, one leg 13 of a second lever 14, which is also bent. The other leg 15 of this second lever 14 is connected via a link 16 to a plate 17, which plate 17 is connected to the pivot shaft 2 of the throttle valve. The pivoting movement of the actuating member 1 is transmitted by the first lever 1 to a second lever 14 which is suspended on a shaft 18 and is further transmitted by a link 16 to a plate 17 via which the throttle valve is is transmitted to the pivot shaft 2 of the The plate 17 is pivoted against the action of the return spring which attempts to return the throttle valve and with it the actuating member 1 to its lower limit position. As mentioned above, the support and the engine are equipped with vibration damping elements 4 made of rubber.

の上に実際上位層する。Between the second lever 14 and the first lever, the lower surface 12 of the first lever 10, especially its front part 19, is connected to the leg 1 of the second lever 14.
3 forms a separate connection between the support and the motor part. During operation, the operator of the machine, for example,
When the mover part or the member connected thereto is pushed by the hand, the mover moves relative to the support, so that the leg 13 of the second lever 14 is moved against the underside 12 of the first lever 10. slide. Usually this means that the actuating force of the actuating member 1 is applied to the leg 13 of the second lever 14, which can change the position of the throttle valve. In the illustrated embodiment, the connection between the first lever 10 and the second lever 14 is as follows:
It is constructed taking into account this force which is undesirable and therefore should be eliminated. The relative movement between the mover part and the support lies in a plane substantially parallel to the cross-section of FIG. This is because the axial direction of the rubber vibration damping element 4 is perpendicular to this plane, that is, the vibration damping element performs a helical movement. In this case, the relative movement is a pivoting movement about a virtual center point in the motor part. Thus, the end of the leg 13 of the second lever 14 traces an arc during such a pivoting movement, so that the lower surface 12 of the first lever 10, especially its outer part 19, has no such arc. If you do this, the leg 13 of the second lever 14 will be
No moment of force occurs on this chest 13 when sliding against the underside 12 of the lever 10. As can be seen in FIG. 1, the outer portion 19 of the underside 12 of the first lever 10 is slightly curved, thereby providing an arc on which the end of the leg 13 slides during the relative movement described above. . As shown in FIG.

ることはない。This means that the frictional force at this point of contact has an orientation approximately along the longitudinal axis of the chest 13, so that no moment of force is created on this leg. This applies in particular when the actuating member 1 is raised slightly from the lower limit position shown, ie when the first lever 10 is adjusted to the normal diaphragm setting. Leg 13 and 1st
The straight portions of the lever 10 are approximately parallel in this position. In the illustrated arrangement of the leg 13, the first lever 10 and its curved lower outer part 19, no moment of force acts on the leg as a result of the relative movement between the motor and the support.

をも、この発明は包含する。This arrangement is illustrative of how the problem of maintaining the throttle valve in a predetermined position can be solved. It can also be observed that a similar solution can be achieved by a variant of this arrangement, for example the second lever 14 can be replaced by a double-armed straight bar, and the combination of the actuating part 1 and the first lever 10 can be replaced by a single It can be replaced with the lever. Certain embodiments of the arrangement described above may also accommodate a different type of relative movement than the previously described pivoting movement about a virtual center point. This invention also encompasses variations of such systems.
